What is Maven?
Apache Maven is a software project management and comprehension tool.
Based on the concept of a project object model (POM),
Maven can manage a project's build,
reporting and documentation from a central piece of information.
How to use this image
Create a Dockerfile in your Maven project
FROM maven:3.3-jdk-7-onbuild CMD ["do-something-with-built-packages"]
Put this file in the root of your project, next to the pom.xml.
This image includes multiple ONBUILD triggers which should be all you need to bootstrap.
The build will
COPY . /usr/src/app and
RUN mvn install.
You can then build and run the image:
docker build -t my-maven . docker run -it --name my-maven-script my-maven
Run a single Maven command
For many simple projects, you may find it inconvenient to write a complete
In such cases, you can run a Maven project by using the Maven Docker image directly,
passing a Maven command to
docker run -it --rm --name my-maven-project -v "$(pwd)":/usr/src/mymaven -w /usr/src/mymaven maven:3.3-jdk-7 mvn clean install
Reusing the Maven local repository
The local Maven repository can be reused across containers by creating a volume and mounting it in
docker volume create --name maven-repo docker run -it -v maven-repo:/root/.m2 maven mvn archetype:generate # will download artifacts docker run -it -v maven-repo:/root/.m2 maven mvn archetype:generate # will reuse downloaded artifacts
Packaging a local repository with the image
$MAVEN_CONFIG dir (default to
/root/.m2) is configured as a volume so anything copied there in a Dockerfile at build time is lost.
For that the dir
/usr/share/maven/ref/ is created, and anything in there will be copied on container startup to
To create a pre-packaged repository, create a
pom.xml with the dependencies you need and use this in your
/usr/share/maven/ref/settings-docker.xml is a settings file that changes the local repository to
but you can use your own settings file as long as it uses
/usr/share/maven/ref/repository as local repo.
COPY pom.xml /tmp/pom.xml RUN mvn -B -f /tmp/pom.xml -s /usr/share/maven/ref/settings-docker.xml dependency:resolve
To add your custom
settings.xml file to the image use
COPY settings.xml /usr/share/maven/ref/
For an example, check the
Running as non-root
Maven needs the user home to download artifacts to, and if the user does not exist in the image an extra
user.home Java property needs to be set.
For example, to run as user
1000 mounting the host' Maven repo
docker run -v ~/.m2:/var/maven/.m2 -ti --rm -u 1000 -e MAVEN_CONFIG=/var/maven/.m2 maven mvn -Duser.home=/var/maven archetype:generate
Build with the usual
docker build -t maven .
Tests are written using bats under the
Use the env var TAG to choose what image to run tests against.
TAG=jdk-8 bats tests
or run all the tests with
for tag in jdk-7 jdk-8 jdk-9; do TAG=$tag bats tests; done
Bats can be easily installed with
brew install bats on OS X
